This 30+15 pfennig semi-postal stamp was issued in Berlin in 1975 as part of the annual Wohlfahrtsmarken (Welfare) series. It features a beautifully stylized illustration of the Yellow Gentian (Gelber Enzian), a mountain flower native to the Alps and Central Europe. Designed with bold yellow blossoms and lush green leaves, the stamp showcases the plant’s natural elegance while contributing to charitable causes through the surcharge (+15 pfennig). Issued by Deutsche Bundespost Berlin, it highlights Germany’s tradition of combining philately with social welfare. This issue is popular among collectors of floral themes, semi-postals, and German commemoratives.
